Diesel Fuel Analysis

Diesel fuel stored on-site for your emergency diesel generators and fire pumps can degrade and become contaminated to the point where it will clog injectors and your diesel engines won’t fire. The turn-over rate for most diesel fuel supplies is very low as the engines are usually only tested for 1 or 2 hours each month. Emergency diesel supplies should be monitored on a semi-annual basis to ensure the fuel is of a quality to meet your emergency needs.

If excess water accumulates on the bottom of the storage tank, algae and bacteria will grow at the water/fuel interface. Dead algae will break away from the bio-mass and can become suspended in the fuel. This bio-mass can clog injectors. If the fuel has been stored for a long time, gum can form in the fuel and also clog injectors.
